Antipasto-Platter Pizza

Preheat oven to 450°F with a pizza stone or baking sheet set on a rack in lowest position. Drizzle 3 tablespoons oil onto a rimmed quarter-sheet pan (9 by 12 1/2 inches). Stretch dough to edges of pan. Drizzle evenly with remaining 1 tablespoon oil; season with salt and pepper.

Spread marinara evenly over dough, leaving a 1/2-inch border. Top evenly with cheese, then mortadella, capocollo, artichoke hearts, olives, and peperoncini. Bake in pan on stone until bubbly and crust is golden brown and set on bottom, 20 to 22 minutes.
